A case of atezolizumab‐induced photodistributed bullous pemphigoid

Immunotherapy has revolutionized cancer therapy in recent years but is associated with unique immunologically mediated adverse effects. Immunotherapy-induced bullous pemphigoid (BP) is an uncommon but established reaction that portends significant management implications as in most instances systemic treatment is required. We report a case of immunotherapy-associated BP in a marked photodistribution, highlighting the diverse clinical presentations of this eruption.
